a casing, a shaft mounted in said casing. disks fixed to said shaft andprovided with' radial slots, inclined rods passing througl.- said slots,revolving hammers pivotaly mounted on said inclined rods between thedisks, 'adjusting means on the shaft and conl radial slots, inclinedrods passing through said slots, sliding disks mounted on the shaft forsupporting said rods, means located on the shaft and connected to one ofthe sliding disks for moving both of said'disks upon the shaft,revolving hammers pivotally mounted on the rods between the xed disks,and means for `loekiifi'g said sliding disks and their carriedinclined-rods in longitudinally adjusted positions.

4. In a pulverizer, a casin a shaft mounted for rotation therein, dis sfixed on said shaft, disks arranged toslide on said shaft, inclined rodscarried by thel slidin disks, which inclined rods pass through t e fixeddisks, revolving hammers pivotally mounted on said rods, and spacingrings arranged between the hammers.

l5. In a pulverizer, a casing, a shaft mounted foi` rotation therein, anadjustable frame mounted on.the`shaft, which' frame comprisesdisksandinclined rods, a series of revolving hammers pivotally mounted andspaced apartlupon the inclined rods, and means carried by the shaftwhereby the hammersare held to move radially with respect to the shaftwhen the frame is adjusted upon.
